Often thinking about how "we just want a place for ourselves with rules that are comfortable for us, it's fine if that's not to everyone's taste but this is our place" got reframed by a particular 'moderate' demographic into "you must mean that you intended for this place to be For Us too, and since we do not like those rules, they must change to our rules instead and you will just have to adapt, things change" and now the folks trying to recover those old boundaries are (sometimes retroactively) accused of "policing" others and "overreacting".
(And racists, don't get it into your head that this is defending your position, because this is not about you. Get fucked.)
